i T0 all whom t 17mg/ con/cern,.-

Be it known that 1 JAMES NV. BONTA, a citizen' of the United States,residing at lVayne, in the county of Delaware and State of Pennsylvania,have invented certain new'and useful improvements in Apparatus forRolling Plate 'or Sheet- Glass, of which the following is aspecilication.

My inventionhas relation to inacliinesfor rolling plate-glass; and ithas for. itsvobgect to so construct the machine that both sides ot theplate can be successively rolled, and thus do away with the unduegrinding necessary when the glass is rolled only on one side, therolling of both sides of the glass removing the irregularitiesnecessitating such grinding.

My invention .accordingly consists of the combinations, constructions,and arrangements of parts, as hereinafter more particu' larly set forthin the specification and pointed out in the claims, reference being. hadto the accompanying drawings', wherein* Figure 1 is a side elevation,partly broken away, showing a machine for rolling both sides ofplate-glass in accordance with my invention. Fig. 2 is a longitudinalsection, partly in elevation, of the same. Fig. '31s an end view orelevation of the saine. Fig. 4 is a like View, partly sectional,illustrating the rotation of the plate-glass and platens. Figs. 5 and 6are respectively an end View and a side elevation of the screws or Wormsfor lifting and lowering the plat-ens and glass. Fig. 7 is a detailView, drawn to an enlarged scale,

showin g end elevation of su pportin g-journals and locking mechanismfor the platens. Fig. S is a longitudinal vertical section ot same withpart of tlie platens in elevation, showing. the locking or movabletubular sleeve released froni the platens. Fig. 9 is a horizontalsection of the same. Fig. ldis a like view showing the lockingtubularsleeve in engagement with the platens. Fig. 1l is a broken elevation ofthe platens. Figs. 12 and 13 are elevations broken away, the formershowing stop-pin and one position of. separating-strip for the platensand the latter showing said pin and another position of said strip. Fig.1l is across-section of laterally-moving guide rails or supports for thcplaten when'moving into position iii the in aeliine for rotation, saidfigure showing such rails or supports in their of actuating mechanismfor laterally moving the guide rail or supports for the platen, thesaine being shown in two different positions. Fig. 23 is a section online 1 l, Fig. 21; and Fig. 24 is a like view on the line 2 2, Fig. 20.

A represents the housings or frame ot' the machine, which preferablycarries an engine vor iiiotor B and has rollers or wheels a, ru'nning onguides or tracks a', so as to .make it portable; but, if desired, it maybe located in a fixed position.

The housings or the machine A consists of a long lower part (02, havingat its upper edges fixed guides or roller-supports a3 andlaterally-moving guides or roller-supports C,

the latter being near the rear end of the niachine, and are of a lengthapproximating that of the platens D D used in the machine, and uponthese guides or supports said platens are reciprocatedto roll theplate-glass.

E E represent vertical standards secured to the housing part a2, andhave open-top bearings e, suitably formed to receive the journals f andeccentrics f on said journals of a pressure-roller F, which is in gearwith the driving-shaft b of engine B, by means of wheels]L12 and Il. Thepresser-roller F is provided with arms f 3 f f3, the upper end of whichhas a pin or other connection f4, with slots or apertures f5 in a curvedbracket f6 concentric with the axis of the presser-roller, said pin orconnection f4 bei iig removable from the bracket f6, so that by movingsaid arins fsf3 to and fro or radially the eccentrics f on thepresser-roller' journals f are moved to set the roller higher or lowerto snit different thicknesses of vplate-glass and also to vary therolling pressure of the saine.

The platens D D are provided with side racks d for engagement with thegear-wheels f7 fl on the presser-roller F, and at one end said platensare provided with side recesses IOO CZ to receive the ends g of racksy', pivoted at g3 to racks G, which are located on the tixed guides orsupports a3 in advance of the platen. a4 a* represent verticalstandards, which support a vertically-sliding frame ll, of any suitableor desired construction, hung upon variable speed or. other screwworms-or actuating mechanism t for raising and lowering said frame, saidactuating mechanism being 1o mounted upon a shaft h', having itsbearings in standards a?, so as to be movable longitudinally by means ofa shifting-lever h2, and has a bevel or other gear wheel h3 inengagement with like Wheels h2, h3, and b4 with the motor driving-shaftl); The wheel h3 is splined to shaft 71.', so-as to admit ot thelongitudinal movement of the latter vwhen shifted and when rotating tolift or lower frame li, as hereinafter described, and said wheel. isheld zo in position to always engage the Wheel b2 by a bracket 7L on themotor B.

In standards a4 is journaled a shaft l, upon which at one end is splinedthe bevel-wheel 1'., having a shiftinglever "to cause said wheel 2 5 ito engage with and disengage from wheel b3. At the other end of shaft iis a gear-wheel t2 and a link i3, which engages the stud-shaft t4 of anidler-gear i5, said stud-shaft i* having an end bearing in a slot t inone end of the 3o frame H, as more plainly shown in Fig. 3.

The lower ends of frame H on each side thereof are provided with insideand approach# 1 ing short journalsor studs h5 and with tubllll boxes he,which inclose said journals,

3 5 the forwarder free ends of the latter projecting beyond said boxes.Y(See more plainly Figs. 7 to l0, inclusive.) g

Vithin boxes hand between them and the journals hare tubular slidingsleeves hl, hav- 4o ing suitable slots hs to admit of their slidingmovement. Mounted in said sleeves and working in slots hg of boxes hareblocks 71.10, on which are journaled eccentrics 7L upon vertical shafts71.12, mounted upon the ends of frame H. The upper ends of shafts'h12are provided with gear-wheels h, engaging with a sliding rackshifting or actuating oar h, so that by moving thelatterin one directionthe eccentricshll and blocks hw are actuated to 5o slide the sleeve h7in one direction, and by moving the bar h14 reversely said eccentricsand blocks are actuated to slide the' sleeve hl in an opposite directionfor purposes herein after-described.

Loosely mounted upon the inner ends of box-es h6 are gear-wheels hl,which engage with the idlers t5, and thence by wheels t2 with shaft I.Said Wheel 7115 at suitable intervals on their inner sides are providedwith tSo-stop-pinsh16 (see more plainly Fig. 3) for a purposehereinafter to be described.

The laterally-sliding rails or supports CA between supports c and thetop edge of the housin The slots c3 are partly straight and partlyangular, as shown more plainly in Figs. 16 and 17, so that when platesc4 are moved in one direction the angular part of its slots c3 actuatesthe studs c therein to lat orally move the roller guides or supports Cin one direction, and when reversely moved said supports C are laterallymoved in au opposite directiou.- A

To actuate the plates c4 they are provided with depending studs o5,passing through slots 'c6 in the top of the housings, and provided witha bar or link connection c7 and a shifting or actuating lever cs. (SeeFig. l.)

"he platens D D are on their ends and at their middle provided withseinioircular projecting journals or supports dg'for engagement with thejournals h5 on the ends of frame H. Both platens are identical inconstruction, and one of them is always in position on the end of theframe H, as shown in Fig. l, andthe other upon the fixed guides c3 infront of the presser-roller F normally to begin operations, which aresubstantially as follows: The presser-roller F is adjusted for thethickness of the glass and the pressure' required for rolling, and afterthe plateglass is laid upon the platen in front of the presserroll,which glass is indicated at X, the pivoted racks g are engaged with therecesses d' in the platen, the movement of the presser-roller enf gagesthe racks d of the platen to move it in the irection of arrow Land as itis so moved the glass is rolled on one side. The platen so moves untilit comes under the platen D', supported upon the frame H, theracks gaudGbeingprovided and keeping in engagement with the presser-roller gearsf7 to admit of thevfull length -of such movement. As soon asthe platen.D arrives at such described position the pivoted racks g are raised outof engagement with the platen by means of a lever g3, (see more plainlyFig. 2,) meanwhile the rotation of the presser-roller having beenstopped or its actuating mechanism being thrown out of gear. The shaft7L is then shifted tolower the frame H and platen D until the'latter IOOIIO

rests upon 'the platen D, with the journals h5 Vrotated without raisingthem to an undue height. lVhen sufciently raised, the move- :ment ofshaft h is stopped and the shaft I is put into operation to rotatewheels hk", the stops or studs h1 of which being in engage-l ment withthe platens, as shown in Fig. lt, the latter are rotated to bring theplaten D on top, reversing the position of the platens and bringing theunrolled side of the glass upi rolled side of the glass uppermost, andmeans permost. The shaftv h is then actuated to lower the platens, thelever cS being meanwhile shifted to return the supports C to theirnormal position to receive the platens. Bar h14 is shifted to unlock thesleeves 717 from the platen boxes or bearings (Z2, and the shaft h isthen actuated to raise the upper platen D from the lower one D', theglass remaining upon the latter. The pivoted rack g is then inoved'intoengagement with the recesses in platen D', and the presser-roller F isthen started, but in a reverse direction to cause platen D to move in adirection the opposite of that indicated by arrow 1, Fig. 1, to roll theother side of the glass.

If desired, the platens may be furnished with pivoted clamps 7a and Za',the former being on one and the latter on the other platen, (see Figs.1S to 20,) for clamping the platens at their sides when rotated. r1`heseclamps Z; may be connected to suitably-arranged vangle-leversI/t12 k3 bylinks 7a4 las, having reacting springs k6, the free ends of the leversk3 being in line with the inner end of the clamping tubular sleeves Zi?,so that when the latter' are moved to clamp the studs or journals (Z2 ofthe platens said sleeves will also actuate the levers k3 toautomatically cause the clamps 7.: to engage with the studs k', and whensaid sleeves are released the reacting springs k6 will act to cause.vthe levers 7a2 k3 to move to unlock the clamps k from the studs 7o.

Instead of using the actuating mechanism for the movable guides C, asabove described, and shown in Figs. 1l to 17, a block Zwith eccentric Z,having a gear connection Z2 with a shifting rack bar, may besubstituted, as shown in Figs. 21 to 2i. It will be noted, therefore,that the details of construction of the machine may be greatly variedwithout departing from the spirit of thel invention; and I do nottherefore limit myself to the construction and arrangement of parts asshown and described, as the essence of the invention is the provision ofmechanism for rolling both sides' of plate-glass successively.

In anotherpendingapplication of even date herewith I have claimed themethod herein described for rolling glass plates, said applicationhaving Serial No. 388,050; and hence I do not herein claim such method.sired, suitably-located heating-pipes m fm may be provided for theplatens to prevent chilling of the glass.

What I claim is* 1. In a plate-glass-rolling machine, the combination ofa presser-roller, a movable platen passing the glass under said roller,avertically-sliding frame having journals carrying a second platen,devices for bringing both of said platens together and locking theirjournais, means for raising and lowering said locked platens, devicesfor rotating the platens and for releasing the same with the unformoving the platen containing the glass.

through or past the presser-roller, substantial] y as set forth.

2. The combination of a presser-roll, a power mechanism, a movableplaten, a normally-stationary platen, and devices for locking theplatens together, raising and lowering them, and rotating them toreverse the sides of the plate-glass relatively7 to the presser-roll,substantially as set forth.

3. The combination of an adjustable presser-roller for rollingplate-glass, a movable platen passing in one direction under said roll,a normally-stationary platen in line with said movable platen when itcompletes its movement for rolling the glass on one side thereof,devices for locking said platens together and for rotating them to bringsaid last-named platen to position for passing the plate through orunder the presser-roll to roll the opposite side of the glass,substantially as set forth.

4. In a plate-glassrolling machine, a presser-roll, two separateplatens, locking devices for supporting said platens with the plateglassbetween them, and devices for rotating the platens, substantially as setforth.

5. The combination of a vertically-moving frame, journals on said framefor supporting a platen, actuating devices for raising and lowering saidplaten and a second platen when brought into alignment therewith, andlocking devices for securing said platens together and forY rotatingthem, substantially as set forth.

G. The combination of a vertically-moving frame, journals securedthereto, tubular sleeves surrounding said journals, means for slidingsaid sleeves, and devices for raising and lowering said frame,substantially as set forth.

7. The combination, with platens D D', means for raising and loweringand for rotating them, of the laterally-moving guides or supports C,substantially as set forth.

S. In a plate-glass machine, a platen supported on end journals, asliding platen adapted to register with said j ournaled platen, anddevices for bringing said platens together, locking them, and rotatingthe same, substantially as set forth.
